IMPRQVEMIENT IN GUN-SIGHTS.

Specication forming part of Letters Patent No. 128,049, dated .T une 18, 1872.

Specification describing a new and useful Improvement in Gun-Sights, invented by JOHN T. LA RUE, of Pleasant Post-Office, in the county of Switzerland and State of Indiana.

This invention relates to the construction of sights for ries and other tire-arms; and consists in a combination front sight and in a back sight adapted thereto, the construction of each being as hereinafter described.

In the accompanying drawing, Figure 1 is a top or plan View of the combination or front sight. Fig. 2 is a vertical longitudinal section ot' Fig. l taken on the line x showing it as when used as an open sight. Fig. 3 is a vertical section throughl the same line, showing it as when used as a globe-sight: Fig. 4is a ver tical cross-section of Fig. 1 taken on the'line y y. showing` it as when used as a globe-sight. Fig. 5 is a vertical cross-section on the same line, showingit closed as when used as an open sight. Figs. 6 and 7 are front and side views ot' the rear sight, so constructed that the front open sight can be seen through it and so that it can also be used with the front sight, Fig. 7 beinga section of Fig. 6 taken on the line Similar letters of reference indicate corresponding parts.

A represents the bed-plate of the front sight, containing cup or cavity B. C is the front sight, which is hinged to the plate A, having -a heel, D, Which bears upon one end of the double flat spring E, seen in Figs. 2 and 3. This spring is confined to the bed-plate at the middle, as seen in those gures. F is a covering-plate, which bears the open sight G.

The front sight folds down into the cup and the plate F covers it, as seen in Fig. 2. This coveringplate has a heel which bears upon the other end of the spring E. The springE acts as a friction-spring to keep the front sight in position when it is raised, its end being pressed up against the heel D of the front sight by the cise form or arrangements of the parts de-.

scribed, as variations may be made without departing from my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent- 1. Two hinged sights, GG, folding one under the other upon a bed-plate A, as described.

2. An article of manufacture, consisting of the sights G Gr, spring E, and plate A, all relatively arranged and constructed so as to be applicable to tire-arms, as set forth.
